Answer:

a = 19

Step-by-step explanation:

-2(a + 3) = -4a + 32

-2a - 6 = -4a +32

<u> +2a        +2a       </u>

-6 = -2a + 32

<u>-32         -32</u>

-38 = -2a

divide by -2

<u><em>a = 19</em></u>

Answer:

a=19

Step-by-step explanation:

-2(a+3) = -4a + 32

-2a - 6 = -4a + 32(<em>Group</em><em> </em><em>like</em><em> </em><em>terms</em><em>)</em>

<em>-2a</em><em>+</em><em>4</em><em>a</em><em>=</em><em>3</em><em>2</em><em>+</em><em>6</em>

<em>2</em><em>a</em><em>=</em><em>3</em><em>8</em><em>(</em><em>Divide</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>by</em><em> </em><em>2</em><em>)</em>

<em>a</em><em>=</em><em>1</em><em>9</em>

An observer 2.5 miles from the launch pad of a space shuttle measures the angle of elevation to the base of the shuttle to be 25
kotegsom [21]

Answer:

Height of shuttle at that instant  = 1.17 miles

Step-by-step explanation:

Refer the given figure.

C is the position of rocket and B is the position of observer.

Here we need to find AC, that is the height of shuttle at that instant.

Using trigonometric rules on ΔABC, we have

      tan25=\frac{AC}{AB} \\\\tan25=\frac{AC}{2.5}\\\\AC=2.5\times tan25\\\\AC=1.17miles

Height of shuttle at that instant = AC = 1.17 miles

On Friday, 27 soccer fans are going to a soccer game. A ticket to the game costs $18 per person. Lunch for all 27 fans costs $17
kirza4 [7]

Answer: x=18(27)+172

Step-by-step explanation:

You have the following information given in the problem:

- The number of soccer fans that are going to a soccer game is 27.

- A ticket to the game costs $18 per person.

- The cost of the lunch for all 27 fans is $172.

- x represents the total cost of attending the game for all 27 fans.

Hayden is organizing his assets and liabilities in the table below. If his net worth is $17,550, then how much does he have in h
77julia77 [94]

Answer: His checking account balance is $2,800.

Step-by-step explanation: What Hayden is doing is comparing his assets against his liabilities. This will determine his net worth. His assets ideally are those that increase his net worth such as landed properties, etc while his liabilities in the simplest language are those debts he is paying off either right away, or that he must pay off eventually.

In other words, to determine his net worth, Hayden has to add up all his assets and from the total derived, deduct his liabilities.

Consider the calculations below;

NET WORTH: $17,550

Add ASSETS  

                         Automobile               13600  

                         Retirement Account   6700

                         Checking Account      XX

Less LIABILITIES

                          Student Loan            4800

                          Credit card debt          750

Net Worth                                            <u>17550</u>

The above table can be simplified as follows;

Net worth = Assets - Liabilities

17550 = 20300 + XX - 5550

Collecting like terms, you now have;

17550 -20300 +5550 = XX

2800 = XX

The Checking Account represented by XX is now calculated as $2,800
